Coal, and what We get front It. By Raphael Mendola.

(S.P.C.K.) —This is a volume in the "Romance of Science" series. The first ch ipter is mainly historical, and, we may add, prophetic. If we put out of consideration the possible coal in South-East England, we get an available stock of 146,544,000,000 tons. The annual consumption is 170,000,000. At this rate we have enough for about eight hundred years. The tendency will probably be to diminish the consumption. The Bessemer process has diminished the quantity used in iron and steel manufacture by five-sixths. About the products of coal there is much curious information. Dyes, perfumes, flavours, and drugs are largely made from it.
